CROSS-REFERENCE TO RELATED APPLICATION

This application is being filed on Oct. 19, 2016 as a PCT International Patent Application and claims the benefit of U.S. Patent Application Ser. No. 62/243,476, filed on Oct. 19, 2015, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

This application is directed to a system for the management and routing of optical fiber cables.

In the telecommunications industry, the use of optical fibers for signal transmissions is accelerating. With the increased utilization of optical fiber systems, optical fiber cable management requires industry attention.

One area where optical fiber management is necessary is the routing of optical fibers from one piece of optical fiber equipment to another. For example, in a telecommunications facility, optical fiber cables may be routed between fiber distribution equipment and optical line terminating equipment. In buildings and other structures which carry such equipment, the cable routing can take place in concealed ceiling areas or in any other manner to route cables from one location to another.

When routing optical fibers, it is desirable that any routing system will be readily modifiable and adaptable to changes in equipment needs. Accordingly, a routing system which would require a high capital outlay and which could not be readily adapted to changes in a customer's needs is not practical. Namely, if routing paths, once established, are forever fixed, the system cannot adapt. Also, and perhaps most important, any routing system must protect optical fibers from damage. In the use of optical fibers, it is recognized that the fibers should not be bent beyond a minimum radius of curvature.

Improvements are desired.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

In general, the disclosure relates to management and routing of optical fiber cables. More specifically, the disclosure relates to an optical fiber cable guide/routing/management system. As will be described in further detail, the optical fiber guide system may be in the form of an articulating guide system that allows the individual fittings of the system to be able to pivot in the up, down, left, and right directions relative to each other to define various paths for the fiber optic cables.

Referring now to FIG. 1, an example fiber guide system 10 having features that are examples of inventive aspects in accordance with the principles of the present disclosure is illustrated.

The system 10 of the present application may be formed by a series of fittings 12 that interlock to define a pathway for the optical fibers/cables. In the depicted embodiment, as shown in FIG. 1, the guide system 10 may utilize a number of different types of fittings 12, depending upon the use and the application of the system 10.

One of the fittings 12 usable within the system 10 is illustrated in FIGS. 2-3. The fitting 12 a includes a base 14 and a cover/retainer 16 pivotally attached to the base 14. The base 14 defines a support surface 18 and a pair of opposing sidewalls 20 extending upwardly therefrom. Cooperatively, the support surface 18 and the sidewalls 20 define an open first end 22, an open second end 24, and an open top 26. The open top 26 is partially blocked by the cover 16 when the cover 16 is in the latched position, as will be described in further detail below.

Each fitting 12 a is configured for attachment to a similar fitting 12 a by a ball/socket type joint or mount. Each fitting 12 a defines a ball mount 28 at the first end 22 and a socket mount 30 at the second end 24, wherein the ball mount 28 of a first fitting 12 a can intermate with the socket mount 30 of an adjacent fitting 12 a in forming the system 10. By providing each fitting 12 a with both a ball mount 28 and a socket mount 30 for inter-attachment, manufacturing efficiencies may be achieved.

Still referring to FIGS. 2-3, each ball mount 28 defines a plurality of pins 32 provided on the surface of the ball mount 28. In the depicted embodiment, four pins 32 are provided, one on the top, one on the bottom, one on the left, and one on the right side of the ball mount 28, wherein all of the pins 32 are generally aligned along a plane generally parallel to the first open end 22 of the fitting 12 a.

Each socket mount 30 defines a plurality of slots 34 extending in a direction from an end 36 of the socket mount 30 toward the base 14 of the fitting 12 a. In the depicted embodiment, four slots 34 are provided that are configured to align with the pins 32 of the ball mount 28. One slot 34 extends along the top, one slot 34 extends along the bottom, one slot 34 extends along the left side, and one slot 34 extends along the right side of the socket mount 30.

The pins 32 and the slots 34 are configured to restrict the otherwise 360-degree rotational motion provided by the ball/socket joint. The top and bottom pins 32 can ride within the top and bottom slots 34, respectively, as two fittings 12 a are pivotally articulated along a first plane P1. The right and left pins 32 can ride within the right and left slots 34, respectively, as two fittings 12 a are pivotally articulated along a second plane P2 generally perpendicular to the first plane P1.

As shown, each of the slots 34 defines a series of detents 38 at various increments along the slots 34. The detents 38 are configured to interact with the pins 32 and provide various stop or fixed positions for the two fittings 12 a as the fittings 12 a are articulated to a desired orientation with respect to each other.

The detents 38 may be spaced to provide stop positions at preselected angle increments, such as every 15 degrees, for the articulating fittings 12 a. The closed ends of the slots 34 provide the maximum deflection angle between the two articulating fittings 12 a.

Each sidewall 20 of the base 14 also defines an angled portion 40 that act to provide positive stops when abutting a similar fitting 12 a as the fittings 12 a are pivotally articulated along the first plane P1.

The cover/retainer 16 is configured to at least partially block the open top 26 of the base 14 to retain the fibers/cables within the pathway created by the articulating guide system 10. In the depicted embodiment, the cover 16 defines a C-shaped latch/catch 42 at each end 44 that allows both snap-fit latching and pivotal motion with respect to hinge posts 46 defined at the top of the sidewalls 20.

As shown, the cover 16 (as well as the sidewalls 20) defines a similar configuration at each end 44 and can be unlatched and latched from either end 44. A tab 48 provided adjacent the C-shaped latch 42 facilitates opening and closing of the cover 16.

FIGS. 4-5 illustrate a fiber guide system 10 formed solely of the fittings 12 a of FIGS. 2-3, wherein the fittings 12 a are shown in various articulated positions. As shown in FIG. 5, the base 14 of each fitting 12 a defines fastener openings 50 through the support surface 18 thereof for mounting the guide system 10 to various fixtures such as support brackets, etc.

In FIGS. 4-5, the cover 16 of one of the fittings 12 a is shown in an open position.

As noted above, the guide system 10 of the present application may utilize a number of different types of fittings 12, depending upon the use of the system 10. FIGS. 6-10 illustrate a fitting 12 b having a different configuration than the fitting 12 a shown in detail in FIGS. 2-5. The fitting 12 b shown in FIGS. 6-10 may be referred to as a universal fitting 12 b since it not only allows mounting and articulation with respect to other similar fittings 12 b to provide a cable pathway between the sidewalls 20′ but also allows for a cable pathway through at least one of the sidewalls 20′ in a perpendicular direction.

As shown in FIG. 6, the universal fitting 12 b defines a first open end 22′, a second open end 24′, and ball and socket mounts 28′, 30′ at the first and second ends 22′, 24′ similar to the fitting 12 a of FIGS. 2-5. However, the base 14′ of the universal fitting 12 b defines a generally longer dimension than that of the fitting 12 a of FIGS. 2-5. Further, in the universal fitting 12 b, at least one of the sidewalls 20′ is formed as a break-out or a knock-out sidewall and includes break-out or knock-out portions 52 for forming a side opening/exit 54 that is generally perpendicular to the open first and second ends 22′, 24′. The side exit 54 provides another option for routing fibers/cables using the system 10. It should be noted that both of the sidewalls 20′ of the universal fitting 12 b may be provided as break-out or knock-out sidewalls 20′ to allow further routing flexibility to the system 10.

One of the sidewalls 20′ of the universal fitting 12 b is shown in FIG. 7 without the break-out portions 52, with the side opening 54 formed.

Now referring to FIG. 8, the universal fitting 12 b is shown with a cable management structure 56 (e.g., defining a trumpet-like configuration) mounted to the sidewall 20′ of the fitting 12 b. The cable management structure 56 defines curved fiber guiding surfaces 58 that are configured to meet minimum bend radius requirements as the cable management structure 56 routes cables away from the fitting 12 b.

The cable management structure 56 also includes cable management fingers 60 for retaining the fibers/cables within the side opening 54 that has been formed by removing the break-out portions 52.

As shown in FIG. 8, in the depicted embodiment, the cable management structure 56 includes attachment features 62 for slidable attachment to the sidewalls 20′ of the universal fitting 12 b.

Still referring to FIGS. 6-8, the universal fitting 12 b defines a split line or indent 64 for allowing the universal fitting 12 b to be split or cut down the middle into a ball-only end fitting 12 c (shown in FIG. 9) or a socket-only end fitting 12 d (shown in FIG. 10).

Such end fittings 12 c, 12 d may be used at the ends of a guide system 10 that is made up of articulating elements if the ends of the guide system 10 are going to be attached to preexisting non-articulating guide systems or fixtures. In this manner, the universal fitting 12 b provides the flexibility to use both a ball and a socket mount 28′, 30′ on the same fitting 12 b or define a ball-only or a socket-only mount at one end and a straight edge at the opposite end for snapping to preexisting, non-articulating structures.

While the inventive systems 10 of the disclosure have been described with respect to cables having optical fibers as transmission media, according to further embodiments, cables having other types of transmission media (e.g., electrical conductors formed of copper or other metal) may be used with the inventive systems 10 provided in the present disclosure.

The individual fittings can be arranged in any orientation relative to the horizontal or the vertical directions, as desired. For example, the open top 26 can be oriented to form an open side horizontally or vertically, or other direction.

The above specification, examples and data provide a complete description of the manufacture and use of the composition of the disclosure.
